Electronic cigarette

Abstract

The invention is related to an electronic cigarette comprises an atomizer and a battery rod connected with each other, a first connector and a second connector connect the atomizer and the battery rod, a fastener is arranged on the first connector, a butting groove is arranged on the second connector, a guide groove extending axially of the battery rod and a clamping groove extending circumferentially of the battery rod and communicated with the guide groove are arranged on the sidewall of the butting groove, the fastener is clamped into the clamping groove, a first magnetic member is arranged on the second connector, and a second magnetic member for attracting the first magnetic member to prevent the fastener-from being rotated back into the guiding groove is arranged on the first magnetic member. The electronic cigarette is firm in connection and simple in operation.

What is claimed is: 
     
       1. An electronic cigarette comprises atomizer ( 10 ) and a battery rod ( 20 ) which are connected with each other, a first connector and a second connector for connecting the atomizer ( 10 ) with the battery rod ( 20 ) are arranged at where the atomizer ( 10 ) and the battery rod ( 20 ) are connected with each other;
 wherein a fastener ( 104 ) is arranged on the first connector, a butting groove ( 220 ) is arranged on the second connector, a guide groove ( 230 ) extending in an axial direction of the battery rod ( 20 ) and a clamping groove ( 210 ) extending in a circumferential direction of the battery rod ( 20 ) and communicating with the guide groove ( 230 ) are arranged on a sidewall of the butting groove ( 220 ), the fastener ( 104 ) is clamped into the clamping groove ( 210 ); and 
 wherein a first magnetic member ( 202 ) is further arranged on the second connector, and a second magnetic member for attracting the first magnetic member ( 202 ) so as to prevent the fastener ( 104 ) from being rotated back into the guiding groove ( 230 ) is further arranged on the first connector; 
 wherein the atomizer ( 10 ) comprises an atomizer electrode assembly, the first connector is the atomizer electrode assembly; 
 wherein the battery rod ( 20 ) comprises an external battery rod electrode ( 201 ), the second connector is the external battery rod electrode ( 201 ); 
 wherein the atomizer electrode assembly comprises an external atomizer electrode ( 101 ), an inner atomizer electrode ( 103 ) which is arranged in the external atomizer electrode ( 101 ), and an atomizer insulator ring ( 102 ) which is arranged between the external atomizer electrode ( 101 ) and the inner atomizer electrode ( 103 ); 
 wherein the second magnetic member is the external atomizer electrode ( 101 ); 
 wherein the first magnetic member ( 202 ) is contained in the external battery rod electrode ( 201 ), and encloses with an internal surface of the external battery rod electrode ( 201 ) to form the clamping groove ( 210 ); and 
 wherein the first magnetic member ( 202 ) is a hollow cylinder, a fastening arm ( 222 ) is formed by axially extending from an end surface of the first magnetic member ( 202 ) towards the external atomizer electrode ( 101 )), the fastening arm ( 222 ) encloses with the internal surface of the external battery rod electrode ( 201 ) to form the clamping groove ( 210 ). 
 
     
     
       2. The electronic cigarette of  claim 1 , wherein the fastener ( 104 ) is a first bulge formed by extending from an outside surface of the external atomizer electrode ( 101 ) towards a direction of away from a central axis of the external atomizer electrode ( 101 ). 
     
     
       3. The electronic cigarette of  claim 1 , wherein the first magnetic member ( 202 ) and the external battery rod electrode ( 201 ) form an integrated structure.
